I’ve not personally used Call Control, so can’t speak to its effectiveness one way or the other.
I’ve not said Republic cannot do it. It seems, to me, Republic is trying another way (preemptively blocking numbers determined likely to be spam without asking end users to build blacklists or whitelists. Those of us frequenting the Community tend to be more hands on (and would be happy to create such lists), however, I’m open to the possibility we don’t represent Republic’s typical customer who might prefer it just be done for them. I also believe one might accommodate both approaches but as Republic has just implemented this feature, perhaps we can give it some time to see how effective it is as it exists?
I think much of the type of information (not limited to this topic) remains available in #tips. The forum software platform has changed over the years but I don’t believe Republic has deleted relevant helpful information. Regarding this particular topic, Google not Republic has hamstrung the ability of third party app developers. I once used a very effective app (Extreme Call Blocker) that’s no longer available because of changes Google has made to Android. The app still works but only on phones running Android 6 (Marshmallow) or earlier.
